Hey guys,

Need to change my gearbox oil but having trouble undoing the filler plug.

It is very tight so I will need to get the breaker bar on there but not sure how...

it is a square bolt... is there a special socket for this or anything? Or do people just use spanners/shifters?

For the record i have already tried: 1 spanner, 1 shifter, 2 spanners, 1 spanner & hammer, 1 shifter & hammer

I will give it a little spray and let it sit overnight and then try again but in the meantime..

any advice would be appreciated!!

Hate to say it but thats exactly why you try take the filler off first dude.

That way incase you cant get it off you can take your car somewhere and get them to get it off, at the moment its stuck on there and you cant even drive somewhere to get help.

Have you searched around for a square socket?

cheers

hmmm thats not original they come with 1/2" female not 1/2" male.

Anyway....get the biggest strongest spanner you can find on it (1/2" or whatever size it is). The find an even bigger ring spanner (any size) and put the ring over the other end of the first spanner so you get a much longer lever.

Make sure you are pushing away from any solid object because you will either:

* crack the filler bolt

* break the first spanner.

Good luck

Mate, just put some strength into it. If you're not strong enough, get stronger, come back in a few months and do again. Or get someone stronger.

I just did mine, and while it was so tight that I felt the blood vessels in my head were going to explode when i was undoing it, I got it eventually.

BTW don't do this, the gearstick goes into the transfer case not the gearbox :(

since when? :rofl: mine does!

and id know - pulled the gearbox out on the weekend and put it back yesterday :(

(you must be talking about GTRs.... not that johnGTS-t or black33gtst or MANWHORE has 4wds) :mellow:

umm yes sorry I am talking about GTR, GTST may be different (probably is since its the same length)

yeah definately different - only four wheel drives have transfer cases :thumbsup:

good to see people helping though (thats why SAU is so awesome)

yeah duncan sorry was talking about gtst = no transfer case so he could of jus filled through gearstick

yeah the guy who rebuilt my gearbox actually told me to just do that!

      This sounds like a perfect excuse to install a Haltech R3.

      I do believe from context he is talking about a S0/S1 R33 RB25 with associated ECU and Wiring for that, and a manual gearbox into a R34 N/A Auto. I don't have the knowledge of all the pinouts and such but my gut feeling from doing my own conversion is to use as much of the R33 stuff that you can. The "car" wiring is quite seperate from the "Engine" wiring when all things are considered. The only things to truly consider 99% of the time is the cluster, reverse lights and potentially disabling the 'not in P/N' immobilizer circuit.

      Rusty roof repair

      A realistic expectattion of how long it has to last also comes down to.... when do you think you will be banned from registering and driving old petrol powered shitters? It's 27 years since that thing was built. It probably rusted out 15 years ago. It was probably repaired and looked OK for another 10. If you do a similarish bodge job now, or perhaps slightly better with some actual rust conversion and glassing, then.... get another 10-15 years out of it, after which you'll only be permitted by the CCP to drive electric cars manufactured in their Shenzen zone anyway.

      Let me assume that the concern over a manual ECU is that the NeoDET that you have was an auto and has an auto ECU. That ECU will not be a problem, but you WILL have to Nistune it. And you would have to Nistune it even if you had a manual ECU, because the turbo ECUs will shit the bed if they do not have all the things that they were told they have to have, to be happy. The big one being the TCS CU, which you won't have in your car. Anyway, with an auto ECU (which I have running my originally auto NeoDET in an R32) Nistune allows you to put in a Stagea image which doesn't panic about the absent TCS, and allows you to override a whle bunch of other annoyances that would otherwise see the check engine light on 100% of the time. Also, you can't wind up the power very far on the stock NeoDET ECUs without Nistune, because the boost sensor gets in the way. Nistune allows you to push that problem much further up the dial. Do you even have the boost sensor with the engine? Without it, you are SOL and will need an aftermarket ECU (or to find a sensor somewhere, god knows where). I can't tell you what the wiring loom differences are in a 34. But what Duncan said above needs to be considered. When you say "loom", does that include the transmission loom? Because you will need to swap out the auto tranny loom for the equivalent manual loom, and get rid of the neutral/park start interlock (basically hot wire it).

      I have had the r3c in for years now, maybe close to 7 years and it has never missed a beat, anyone can drive it. Super easy to drive around town, the hotter it gets does get a little hard but it holds the power easy as
